Description of problem:
there is hardcoded limitation that enforce to deploy only single node of odl,

 if $step >= 1 {
    # Configure ODL only on first controller
    if $primary_controller == downcase($::hostname) {
      include ::opendaylight
    }
  }
 
instead of using "if $primary_controller == downcase($::hostname)", will be better to add use:
 if $primary_controller == downcase($::hostname) and $enable_ha == true
this will allow the user to pass the argument of enable or disable this feature from the tripleo env files
